Wow. Did not know that. We use paherps.com for our local guys. Thank you.
Maybe peep(pun intended) it out? There are some fairly rare and spectacular frogs and sallymanders i need help catching lmao. It alsolutely blows my mind watching a little swamp frog(where i found them) cling to vertical grass like a champ.
